I've got data for duration of calls for a number of days. I've created a Pivot table that groups dates by week number and right now shows subtotal SUM OF DURATION, i.e. the total time for the whole week.
However, I would like the weekly subtotal to show the average daily duration (e.g. day 1 - 3h, day 2 - 5h, average - 4h).
Is this possible?
Thank you!
